,FIREQPLACE PUBLMAGAZ'INE s'rovn.

Be itknown that I,JOHN J. MYERS, of the city of Baltimore, in the State of Maryland, have invented certainV new and'useful Improvements on Fire-Place Fuel-Magazine Stoves, and `I do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, nlaking part of thisspecication, in whieh- Figure 1,` plate 1, is' a` front -clevati'on lot' the irnproved stove.

Figure 2, plate 1, 1s a top view of the stove, with the rear portion of the top broken away.

Figure 3, plate 2, is avertical section, taken centrally through the lstove from side to side.' e i Figure 4, plate 2, is a vertical section, taken centrally through the stove from fro'ut to rear. 'f;

Figure 5, plate .2, is a section takenin the horizon` `tal plane indicated by dottedlinesn figs. 3 and 4.

Figures Gland 7, plate 2, are -different views, show ing the manner of connecting together' the screen-sec-` oi' applying the same to the top-feed magazine.

Similar `letters of reference indicate corresponding lparts in the several figures.

i This invention relates to certain novel `improvennen ts on that class of magazinestoves which is adapted for being arranged in tire-places, so-as to partly projectl therefrom. `Such stovesV require to ihevery short, in

` order to be rcceiveddin ire`places as at present constructed; and for the purpose of giving the greatest possible vertical capacity to the magazines, the latter e have been carried nearly to the top-of the upper sections oi' thestoves, and feed-openings provided through the tops of said sections and magazines, fonallowingI the latter to he filled with fuel. The nature of `my invention consists- First, in the gaseescape passage of the feed-chute for a' magazine nre-place stove.

Second, it consists inthe curved door for closing the gas-escapepassage ofthe chute and the feed-passages vthrough the top. ofthe stove and magazine.

Third, itconsists-'in attaching this curved door to the stove, in such amanner that itforms a perlnanent part of the stove, and yet is movable, so as to open the feed-openings ofthe stove and magazine, and also the gas-passage of 'the chute. It also consists in arranging said door to open and close by aV movement in the path oifa vertical circle.` e e Fourth, it consists iu the combination of ornamental air-distributing screens, either stationary or movable,

with` a curveddoor, which'is a permanent part of the stove, but 1 movable, so as to open andclose the gaspassage and-the feed-opening of the stove and maga- 4 l y l zine. e

Fifth, it consists in attachingethe screen, or a section thereof, to the curved door, so as to be easily dis-v connected fromthe same when desirable.

` Sixth, iteonsists in the combination of a series ot' short air-heating pipes, the combustion-chamber cominunicating at the back 'with said pipes, the hollow base, the return-columns, and the-damper serving to Inake'a direct or indirect draught.

Seventh, it consists in the combination oi' the dampper section of the stove, and the main draught-tine,` whereby a direct escape for gas into the draught-flue from the chute, when the feed-door is opened, is at all times maintained, whether the damper -is adjusted for a direct or indirect draught.

.i Eighth, it consists in the due-extension of the yupper section of the stove, yfurnished with a gas-escape and with a damper, in combination with the lower com-l bustion-chamber, which is furnished with downward fines, into which the products et' combustion first pass when the damper is closed.

To enable others skilled iii the art to understand my invention, Iwill describe its construction and operation.

In the accompanying drawings- A represents the hollow Vbase-section of the nre-- place stove, which has'itsash-chamber b separated from the space c', by means `of' a semicircular divisionplate.

The space c communicates with the space enclosed by top section C, Joy means of the vertical side columns E E, and short horizontal pipes da, as shown in figs. land 3. i

B is the section which encloses the combustion-chamber, and which is provided with mica-light windows or doors, or both windows and doors. This combustionchamber contains the vlirepot or fire-brick lining, and has. a grate at its base. p

' The upper back portion of the comb'ustion'chamber is extended horizontallybackward, as shown .at B', figs. 4 and 5, for the purpose of conducting the products of combustion into the upper end ot' a number of descending fine-pipes, S, which lead from said back extension-B"down, and empty into the flue-space c',

in the'basev A ci' the stove. These pipes S .are small in diameter, and are isolated from the combustionchamber section and'from each other, so that air canl V circulate freely about them. Theyv afford a large amount of .heat-radiating surface, for` heating air 4iiowng into the spacejat the back of the stove.

Thev combustion-chamber section B B is capped by a horizontal plate, on 'which is supported the top sec.- t-ion C.

This section encloses'a chamber, which is separated .stove within the chamber C, is the upper magazine-section F. lhe lower section F of the magazine'may incline backward, as shown in iig. 4, for the purpose of' exposing a larger amount of incandescent fuel in front of it than behind it, and thereby throwing more' heat Vtoward the .front of lthe stove than toward the back. rlhe nppersecton of this magazine is preferably made crowning or hemispherical, so as to leave a free space all around and above it, except at the point where the feed-passage leads into it.

The feed-passage k is made in the form of an inclined chute, leading through theV front Vconvex portion of the top ot' section C, into the top of section F.

This chute is` formed by means of two vertical sideplates Ir lr, and an vinclined lip, r', which close the sides and` bottom of the passage, but leave the upper side open and in communication withvthe space fu, above the magazine-section F.

' lhe opening leading through the convexity of the section() is provided with a curved sliding door e, which moves in and is guided by grooves f, formed in the side-plates lr o', as shown iu figs. 4 and 6.

The grooves f are made in the arc of a circle, of such length as will allow the door e to be depressed far enough to expose the entire passage k, and also to allow the door to be moved upward and inward far enough to shut the opening leading into the passage or chute 1.', as well as that leading from this passage or chute-into the space v, between the magazine-section F and the outer casing C.

When the doore is shut, its upper edge abuts against a lip, I, formed on the, magazine-section F, anda lip formed on the door receives a lip, s, which is formed on the upper edge of the top plate of section C, thus preventing leakage of gas.

"lhe upper lipped edge of'the opening through section C, considerably overhangs the corrcspondingedge l ot' the opening into the magazine-section F, thereby bringing all the gas rising out of the magazine, under the infuence of the draught, into the exit-pipe. 4

At the back of the top section C, outside thereof, a chamber, K, is constructed, which communicates, at its bottom, with the back horizontal extension B of the combastion-chamber, through an opening provided with avalve, J.

Near the top of the chamber K is an opening, t, leading out ot' the top section C, and through the top of chamber K is an opening leading into the main fluepipe H.

This pipe partly encroaches upon the top of section C, so that when the damper or valve J is shut, as shown in tig. 4, the products of combustion, after circulating through pipes S, base-tlne c', columns E E, and the flue-space in section C, will escape freely from the latter into said pipe H.

D represents the upper port-ion of the` frame, or lireboard, and indicates that portion of the stove which" projects ont into the room.

To this frame I), two sections, or segments G G, are permanently secured, which form, in combination with an intermediate segment, G', a perforated screencover for hiding from view the to'p of section C, and giving an ornamental appearance to the top of the The intermediate segment G is secured to an arm, 11.,.1ising from the cover c, so that bothof these covers move together in opening or closing the feed-passage leading int-o the magazine.

The slot c, made through the front of section O, allows the arm h to move down with the covers.

By thus connecting the cover ewith the screensection cover G, there is in fact but one movement to be made to open or to shut the feed-passage and gaspassage, whichl renders the operation very simple and convenient.

pera tion.

When lire is first made on the grate, the rod j', extending from damper-rod j to the front of the stove, is moved, so as to raiseth-e damper .I from its passage, and allow a direct thaught fromthe combustionchamber through back extension B', through the fluechamber K, and out through the main escape-flue H.

When the ire burns freely, and a direct draught is no longer required, the damper J is shut, as shown in iigs. 2 and 4.

The direction of the products isthen'as follows:

They pass into the back extension B', and are equally distributed to the pipes S, down which they pass into the base-due c'. Here the products are divided again, one-half passing to each'one of the columns E, thence through these columns to and through the short pipes'a a, into the fine-chamber in section C.

Upon entering this section C, the products are drected a little forward by the two vertical wings 'i i, on opposite sides of the opening t. The products then pass back between said wings, and escape into the main ue H.

It will be seen from that part ot the above description which relates to the top-feed magazine, that I prevent the escape of gas into the room, when the feed-door is removed from the feed-passage, by bringing the space above the coal in the magazine under the influence of the draught of the main lne of the stove, which draught will overcome any tendencyof the gas rising into thel room.

I also adopt a single plate, cover, or door, to shut the feed-passage, as well as the gaspassage, and thereby obviate an' inconvenience whichwould attend the handling of two disconnected doors or covers.

'I employ a chute, that is to say, a passage which is closed on three sides, for two purposes, namely, that the coal may be guided and directed into the fuel-mag azine, and that lateral currents, which would be liable tovdirect gas into the `room,vshall not cross the `feedpassage.

I' also connect to the cover e, which closes both the feed-passage and gas-passage, the screen-section G, so that bot-h of these parts move together.

This Amay be done, as shown'in figs. 4, 6, and 7, by passing the arm h through a slot made through the section G', and using the cross-key g above the bridge g. The arm h has shoulders formed on it, o'n which the section G rests and is held.

I do not limit my invention to making a part of the screen stationary, as I may have the Whole screen at' tached to the curved plate e. l

It' desirable, the central portion G' may be simply a raised solid ornament. cast on and with the cover e, such ornament being formed on the same curved line with the screen-sections G G, and the streen-sections v G G being either stationary, as shown, or movable with the door or cover, in which latter case the screens willbe castlike wings on each edge of the curved cover.
